Has anyone seen the System Software 4.10 & GPS 5.00 on Garmin Express?

As mentioned by  on Jan 15, 2021 on this forum, System Software 4.10 & GPS 5.00 should appear on the Garmin Express software for Descent Mk21/Mk2. However, I do not not find them on my Garmin Express.app 7.2.0.0 running on macOS 11.1.
